The final autopsy report was issued by medical examiners inSan Bernardino County two months after King, 47, was foundsubmerged at the deep end of a swimming pool at his home inRialto, 50 miles (80 km) east of Los Angeles.

The county coroner ruled the death an accidental drowningand listed "alcohol and multiple drug toxicity" as contributingcauses, saying that traces of cocaine, PCP and marijuana werefound in King's body.

Rialto police Captain Randy De Anda told Reuters the case isclosed.

"Our investigation is now concluded," De Anda said. "Theconclusions that our investigation revealed have been reinforcedby the autopsy and toxicology report."

The 19-page document, prepared by county medical examinerDr. Frank Sheridan, ruled out suicide or foul play.

King "was in a state of drug- and alcohol-induced deliriumat the time of the terminal event, and either fell or jumpedinto a swimming pool," the coroners wrote.

King had been drinking and smoking marijuana with a friendthroughout the previous day and into the night before his deathon June 17, according to the report.

The effects of the drugs and alcohol, combined with anenlargement of his heart's main pumping chamber, probably causedan irregular heartbeat, "and the subject, thus incapacitated,was unable to save himself and drowned," the coroners concluded.

His death came two months after the 20th anniversary of LosAngeles riots triggered by the acquittal of four white policeofficers prosecuted for beating King, who was black, in aconfrontation a year earlier that was caught on videotape andwidely replayed.

During the riots, which left over 50 people dead and causedmore than $1 billion in property damage, King famously appealedfor calm in a televised appearance in which he asked: "Can weall get along?"

The case helped bring attention to the issue of racialprofiling by law enforcement and was a catalyst for far-reachingreforms in the Los Angeles Police Department (LAPD).

'BABY, COME HELP ME'

The autopsy report revealed new details about the franticmoments just before and after King ended up in the water.

She saw him fall backwards into a planter, and when she wentto get her phone to call police, she heard a splash. She rushedoutside to find King "face down at the bottom of the deep end ofthe pool," the report said.

Unable to go to his aid because she was a poor swimmer,Kelly used a pitchfork and a garden hoe to jab at him in afailed attempt to rouse King.

Police retrieved his lifeless body from the water, andefforts to resuscitate him were futile.

King, who long struggled with drug and alcohol abuse,financial difficulties and legal problems, had this yearpublished a memoir entitled: "The Riot Within: My Journey fromRebellion to Redemption."

King's March 1991 beating occurred after he was pulled overfor speeding by Los Angeles police, who had pursued him forseveral miles before he stopped and got out of his car.

Grainy video footage of King being kicked and struckrepeatedly with batons by LAPD officers while he lay on theground provoked a national uproar and charges of raciallymotivated police brutality.

Two of the four white officers acquitted of state charges bya jury the following year were later convicted of federalcharges and sentenced to 30-month prison terms. A civil jurylater awarded King $3.8 million in damages.
